Cons
Con Notifications get muted after inactivity
New message notifications stop getting pushed if the application isn't opened for some extended period of time (seems to be around a week or so)
Con WeChat complies with China's requirements to hand over data
Con Conversations and chat groups aren't ported to new devices
Messages are stored on each device, so shifting to a new device means losing all the previous conversations, as well as an inability to post in previous chat groups until someone else posts there and you're alerted of a new message.
Con User base outside of China is comparatively small
While WeChat has over 400 million users the majority of them are in China. Adoption in other markets has been slow.
Con Needs access to your phone number and contacts to work
Con Single device
Signal can only be registered to one mobile device at a time. But you can link Signal to Signal Desktop.
Con Servers hosted in the US
A security risk due to National Security letters, which require giving up data to the US state, and making it illegal to disclose that.
Con Unreliable notifications
Sometimes messages won't be received if the Signal app has been closed for a long time or hasn't been opened after booting the device.
